Chris Packham a74c313aca i2c: mpc: Use atomic read and fix break condition ... Maxime points out that the polling code in mpc_i2c_isr should use the _atomic API because it is called in an irq context and that the behaviour of the MCF bit is that it is 1 when the byte transfer is complete. All of this means the original code was effectively a udelay(100). Fix this by using readb_poll_timeout_atomic() and removing the negation of the break condition.
